YouTube is a resource for free full-length films in 4K resolution, including the films "Biosphere" and "The Paranormals"; MitchMartinez.com also offers 4K films. MitchMartinez.com offers more than 1,500 4K stock videos for free.
To verify that a film on YouTube is available in 4K resolution, look for the "4K" designation in the box located under each search result. Many free full-length films online advertise 4K resolution in their titles or descriptions but are actually lower-resolution HD films. For those with the hardware capacity to display 4K video, YouTube's verified resolution information ensures that users see 4K content. Additionally, users can select the gear icon in the lower-right hand corner of a YouTube video to change or verify a video's resolution.
All stock footage on MitchMartinez.com is available for use in commercial or non-commercial projects after signing a release waiver.
